Open access is a movement to ensure that access to research is widely and quickly available to all, regardless of ability to pay. With today's technology, this is possible.
For authors, Open Access typically comes in two flavors:
>Gold OA: Authors publish their papers in an open access journal that provides immediate access to its articles via the publisher's website. Authors may have to pay have to pay a fee to publish in these journals, but not always. Often that fee can be covered by a grant or waived, depending on the circumstances.
>Green OA: Also known as self-archiving, this OA option means that authors publish in any journal and then self-archive a version of the article for free public use. Publication of this article could be on a webpage, but it is often in an institutional or discipline-specific repository.
